F2 Underwater Primer - Foundation for Lasting Protection
High-bond, biocide-free primer for marine surfaces
The F2 Underwater Primer is a high-performance epoxy primer designed specifically for underwater surfaces. It seals and smooths existing coatings or substrates, and ensures a secure bond for the F2 base coat that follows.
Seals and Protects the Hull
Locks in old paint and substrates, preventing moisture ingress and corrosion while creating a uniform base for coating.
High Adhesion for F2 Coating
Chemically etches and clings to the hull, providing a tough base for the F2 Adhesive Coat to bond securely.
Marine-Safe & Universal
100% biocide- and solvent-free, compatible with fiberglass, metals, and old antifouling paints for versatile use.
Quick Drying & Easy to Use
One-part primer, dries to touch in ~3 hours. Apply with roller or brush, no critical overcoat window.
Application
After prepping your hull (sanding and cleaning), apply one full coat with a medium nap roller and brushes for tight spots. Dry time ~3 hours at 70°F. Ensure surface is dry and clean before base coat.
